Hey, Dhabih,
One question: What resolutions do you work with? You didn't mention that in your tutorial...
I usually sketch at small res's, and then resample at about 6 times the initial res. up and over. (600x600 --> 2500x2500) That's where I do the clean line, detail, etc. That gives you a lot of freedom on the detail.=)

I work at the size the final piece will be in. And thats usually 800x600 or there abouts. A month ago i started on a drawing that was really big like 2500+ but it got lost with the crash. So i'm still not sure which one i'll continue with. Maybe i'll try working large and downsizing, but so far, what you see is what you get. Also when its not that big, detailing is easier for me cause you dont have to be too perfect.

I agree with Dhab -- I find it best to work in the same resolution as the finished product will be. I know a lot of people like to work bigger and resize down, but I feel that is cheating and makes you more sloppy. Nothing wrong doing it that way, I just don't feel honest when I do it.

And for textures and other things that aren't hand-drawn with brushes, I find resizing down no matter what method (bicubic/etc) will always result in the loss of sharpness and detail.

I tend to be analytical of everything around me, looking at it to find out how it was made or composed. I could tell that Dhab used a 1:1 ratio for his work, and he is damn good at it. After a while of looking at things you begin to break them down and your mind automaticly catagorizes them into simpler parts. Soon you will be looking at things and thinking how simple it is to do... until you try and actualy make it instead of make it in your mind. I better stop while I'm ahead as I think I have typed too much

I, personally, work with images ranging from 1000x1000 to 2000x2000, because I make my images to be printed at 150 dpi, about 10 inces high each. A4 size, that is. Recently, though, I've been working with smaller image sizes. I've found 1280x1024, the size of my desktop is good for me, it lets me fill the whole screen.

Jack was drawn initially with just smooth skin and only had the shading for the shape of the face and not the texture. After that was done I then went through and drew in the skin texture by putting a lighter brush over each area. This is another thing i'll touch on in the next tutorial. Which i decided i wanna start working on, as soon as i come up with an idea for a drawing. (btw, dont hold your breath these things take long, at least for me)
